Popular questions

  1. Why is my s*** green?

    Foods or drinks colored with Green S (E142) or other green/blue dyes can pass through and temporarily turn stool green; this is usually harmless and resolves once the colorant is out of your system.

  2. Are s&h green stamps worth anything?

    That’s unrelated to E142—Green S is a synthetic green food dye; S&H Green Stamps were a retail loyalty stamp and not a food additive.

  3. What were s&h green stamps?

    They’re not related to E142; they were a U.S. trading-stamp loyalty program, unrelated to the Green S food dye.

  4. What are s&h green stamps?

    They’re not related to E142; they’re trading stamps from an old retail loyalty program, not a food color.

  5. What does it mean when your s*** is green?

    In places where Green S (E142) is allowed (EU, Australia/NZ), eating foods dyed with it can make stool appear green; if it persists without recent intake of dyed foods, consider speaking with a healthcare professional.

    That’s unrelated to this additive; E143 (Fast Green FCF) is a synthetic green food dye used as a colorant—approved in the U.S. but not permitted in the EU.

  2. Can i travel 3 months before my green card expires?

    This concerns immigration, not the additive; E143 (Fast Green FCF) is an artificial green dye used to color foods and is not allowed in the EU.

  3. Why has my poop been green for 3 days?

    Ingesting artificial food dyes such as E143 (Fast Green FCF), which is poorly absorbed, can turn stools green as the color passes through. If it continues without dye-rich foods or you have other symptoms, seek medical advice.

  4. Who was the green symbiote in venom 3?

    That’s about a movie character; E143 (Fast Green FCF) is simply a synthetic green food dye and has nothing to do with symbiotes.

  5. Why is toxin green in venom 3?

    That’s a movie design choice; E143 (Fast Green FCF) is a sea green synthetic food dye whose color comes from its light absorption, and it isn’t related to character colors.
